검증된 단계별 안내1
Step 1: Understand the question by identifying the key terms. The problem is asking about a type of cell division that involves two consecutive rounds of prophase, metaphase, anaphase, and telophase (PMAT).
Step 2: Recall the definitions of the options provided: Meiosis, Binary fission, Cytokinesis, and Mitosis. Meiosis is a specialized form of cell division that reduces the chromosome number by half and involves two rounds of PMAT. Binary fission is a simple form of cell division in prokaryotes. Cytokinesis is the process of cytoplasmic division, and Mitosis is a single round of PMAT for somatic cell division.
Step 3: Focus on the characteristic of 'two consecutive rounds of PMAT.' Meiosis is the only type of cell division that includes two rounds of PMAT, known as Meiosis I and Meiosis II.
Step 4: Compare the other options to confirm they do not fit the description. Binary fission does not involve PMAT; it is a simpler process. Cytokinesis is not a type of division involving PMAT but rather the division of the cytoplasm. Mitosis involves only one round of PMAT.
Step 5: Conclude that the correct answer is Meiosis, as it uniquely involves two consecutive rounds of prophase, metaphase, anaphase, and telophase.
